I meant to ask what vendor of motherboard do you have (reference design or Striker II Extreme)? With that said it sounds like you have the S2E, if so I'd just stick with using the Windows based "Asus Updater" software (depending on what BIOS you currenlty have because if you have a very old version you need to use a different method)? Now besides using the Asus Updater in Windows do you happen to have a thumb/USB drive? You could just put the BIOS file on that and then use the "EZ Flash" program through BIOS to update the BIOS file. I'm sorry if you have already posted what board your using (its quite late here and I'm tooo tired to go searching through earlier pages of the thread)!
